摘要： A laser beam for ultrasonic generation is emitted to a reflector/vibrator to generate an ultrasonic wave, and the ultrasonic wave is transmitted to an object to be inspected. The ultrasonic wave transmitted to the object is reflected at a flaw inside the object, returns to the reflector/vibrator and vibrates it. The vibration is detected using a laser beam for ultrasonic detection to find flaws inside the object. According to the present invention, ultrasonic flaw detection can be made for reflecting materials having corrugations on their surface or having a low reflection factor of light, and for objects made of materials which cannot easily generate the ultrasonic wave by the laser beam. For such materials, the conventional method has not been useful because it adopts the direct application of the laser beam to the surface of the object to generate the ultrasonic wave.

摘要： A method and apparatus for measuring uranium isotope enrichment in a sample uranium solution. In the invention, the concentration of uranium in the uranium solution is determined by K-edge densitometry. The quantity of uranium-235 in the uranium solution is then measured by detecting the gamma rays emitted from the uranium-235 by using a high-purity germanium detector. A value of the uranium isotope enrichment is obtained from the ratio of the quantity of uranium-235 in the uranium solution to the uranium concentration. The invention is designed to provide the improved construction of a radiation source suitable for the K-edge densitometry and to provide the accurate measurements by correcting any error in the measured quantity of uranium-235 in the uranium solution due to the self-absorption of the gamma rays emitted from the uranium-235.

摘要： A method for homogeneously mixing a uranium/plutonium mixed oxide which is used for the preparation of a uranium/ plutonium mixed oxide fuel. The method comprises weighing a uranium oxide powder, a plutonium oxide powder, and a dry recovered powder prepared by grinding a uranium/plutonium mixed oxide sinter so as to give a predetermined plutonium enrichment; roughly mixing these powders together by means of a mixer; pulverizing and homogeneously mixing the roughly mixed powder by means of a jet mill (16); discharging the homogeneously mixed powder together with compressed air from the jet mill; and separating the mixed powder from the air by means of a first-stage cyclone (18) to recover at least 90% of the discharged powder.
